Saudi contractors use bitumen sheets more than any other membrane on villas, schools, government buildings and industrial foundations, and the product is part of the broader range of waterproofing systems used in Saudi Arabia. This page focuses on choosing and buying the sheet: the polymer, the reinforcement, the finish and the paperwork. For concrete tanks where a sheet cannot be bonded on the water side, crystalline waterproofing treatments work inside the concrete, while liquid roof and deck membranes suit roofs crowded with plant. Information here was checked as of October 2026.

What kinds of bituminous waterproofing do Saudi suppliers offer?

Saudi suppliers offer locally made APP and SBS torch-on sheets, imported self-adhesive sheets, oxidised bitumen sheets for economy work, and bitumen primers and coatings. Match the product to where it goes and how much the structure moves.

Product	Where it is used in KSA	Key specification
APP torch-on sheet	Villa and school roofs under tiles or screed, raft and footing waterproofing	Thickness, polyester mat weight, heat resistance, film or mineral finish
SBS torch-on sheet	Retaining walls, tunnels, metro boxes, decks that crack or move	Cold flexibility class, elongation, reinforcement, double layer where specified
Self-adhesive sheet	Basement walls, refurbishment, sites where open flame is banned	Primer, application temperature range, lap sealing, protection board
Oxidised bitumen sheet	Low-cost roofs and secondary areas	Reinforcement, thickness; check it is accepted by the consultant
Bitumen thick coating or emulsion	Footings, grade beams, back of retaining walls	EN 15814 declaration where specified, dry film thickness, cure before backfill

The polymer matters most. APP gives a stiffer sheet that resists softening in strong heat; SBS gives a rubbery sheet that stretches over cracks and joints. A data sheet issued by Stoncor Middle East for Tremproof SBS lists 4 mm and 5 mm sheets with cold flexibility grades of minus 15, 20 and 25 degrees Celsius and plain, slate, aluminium, geotextile and sand surfaces, which shows how many variants one product code can hide. Specify the full code, not just "4 mm SBS". For roofs with exposed single-ply options, compare against roof waterproof membranes.

How do Riyadh heat and sabkha ground affect bituminous waterproofing in Saudi Arabia?

Inland, the risk is heat: softened rolls, fast-drying primer and sun-aged sheets. On the coast, the risk is ground: salty, high groundwater that attacks concrete and finds any gap in a lap.

Hot inland roofs

On Riyadh, Qassim and Hail roofs, slab temperatures in summer limit the hours a crew can prime and torch, and freshly primed concrete dries far faster than data sheet figures measured at moderate temperatures. Prime only what will be covered the same morning. Roofs should finish with a mineral or aluminium cap sheet, or be buried under XPS insulation boards and tiles, so the bitumen is not left to bake.

Sabkha and coastal foundations

Around Dammam, Al Khobar, Jubail and low parts of the Red Sea coast, footings and rafts often sit in saline sabkha ground. Here the sheet is one layer of a defence that also needs sulphate resisting concrete and the right concrete admixtures. Fully weld every lap, carry the sheet up past the highest expected water level, and protect it with board before backfill so stones do not puncture it.

Storage and delivery

Rolls arriving on open trailers in summer should go straight into shade, standing on end. The Tremproof SBS sheet, for example, warns that sun and heat considerably deteriorate stored rolls. Reject rolls that are flattened, stuck or past their shelf life.

Which standards and approvals apply to bituminous waterproofing in Saudi Arabia?

Saudi buyers meet three layers of requirement: the Saudi Building Code for the building, SASO rules and SABER certificates for imported products, and the product standards the consultant writes into the specification. As of October 2026 these are the ones that appear most often.

Requirement	Scope	Issued by
Saudi Building Code	Design of foundations, basements and roofs	Saudi Building Code Center
SABER product and shipment certificates	Imported membranes covered by a SASO technical regulation	SASO
BS EN 13969	Bitumen damp proof and basement tanking sheets	CEN, published in the UK by BSI
BS EN 13707	Reinforced bitumen sheets for roofs	CEN, published by BSI
EN 15814	Bitumen thick coatings for structures below ground, not roofs	CEN
BS 8102:2022	Below-ground protection, Type A barrier systems	BSI code of practice

Saudi-made sheets do not need an import shipment certificate, but imported sheets do, and the HS code decides which SASO regulation applies; ask the importer to confirm before the order is placed. Our guide to SASO and SABER certificates explains the process. Some local data sheets and retailer listings quote ASTM test methods or Saudi standard numbers; ask for the test report behind each figure rather than relying on a listing.

Who supplies bituminous waterproofing in Saudi Arabia?

Saudi Arabia has its own bitumen membrane factories, so local sheets are the default on most building work, with European and regional brands used where the consultant names them or a long system warranty is needed.

Brands in our directory include Awazel, a Saudi maker of torch-on and self-adhesive bitumen sheets, Fosroc Proofex Torchseal APP membranes, Tremco Tremproof SBS sheets from its Middle East business, Soprema bituminous sheets for roofs and below grade, Index APP and SBS membranes from Italy, Danosa SBS sheets and drainage layers, BMI Icopal bituminous roofing and GCP Bituthene self-adhesive sheets.

When comparing offers, ask whether the seller is the factory, an authorised distributor or a trader. Factories and authorised distributors can issue system warranties and arrange applicator approval; traders often cannot. Ask for the data sheet for the exact code, test reports, SABER documents for imports, the applicator approval and the handover test (usually a flood test on roofs). For broader supplier checks, read how to source industrial suppliers in Saudi Arabia.

What affects the price and lead time of bituminous waterproofing in Saudi Arabia?

Saudi-made APP sheets are usually the lowest-cost and fastest option; imported, specialist and self-adhesive sheets cost more and take longer because of shipping and certification.

Local or imported. Imports add freight through King Abdulaziz Port in Dammam or Jeddah Islamic Port, plus SABER paperwork.
Polymer and thickness. SBS, low-temperature grades and 5 mm sheets cost more than standard 4 mm APP.
Finish. Mineral and aluminium cap sheets cost more than film-faced sheets laid under screed.
System depth. Double layers, protection boards, drainage sheets and screeds raise the installed price.
Site location. Remote sites and giga-project logistics add delivery time and cost.

Frequently Asked Questions — Bituminous Waterproofing

Are bituminous membranes made in Saudi Arabia?

Yes. Saudi Arabia has domestic factories producing APP and SBS torch-on sheets, self-adhesive membranes and bitumen primers, and Saudi-made sheets are the default on much building work. Imported European sheets are used where a consultant names a specific brand or the project needs a particular system warranty.

Do imported bitumen membranes need SABER certificates in Saudi Arabia?

Imported bitumen membranes entering Saudi Arabia need SABER shipment certificates, and a product certificate where a SASO technical regulation covers them. The HS code decides which regulation applies, so ask the importer to confirm the requirement before ordering. Locally manufactured sheets do not go through import certification.

Which bituminous membrane suits Riyadh roofs?

On Riyadh roofs, APP sheets with a mineral or aluminium cap, or any bitumen sheet buried under XPS insulation and tiles, perform best because they are shielded from heat and sun. Plain film sheets should never be left exposed. Work early in the day and prime only what will be covered.

How do you waterproof foundations on sabkha with bitumen sheets in Saudi Arabia?

On sabkha in Saudi Arabia, use a fully bonded SBS or APP sheet with welded laps on all faces of footings and walls, carried above the highest water level and protected by board before backfill. Combine it with sulphate resisting, low permeability concrete, because the sheet alone does not protect the concrete from salts.

What is EN 15814 and does it apply to Saudi projects?

EN 15814 is the European standard for polymer modified bitumen thick coatings used to waterproof structures below ground; it excludes roof products. Saudi consultants may name it for bitumen coatings on footings and walls, so ask for a declaration against it where the specification calls for one.

What is the difference between torch-on and self-adhesive bitumen sheets?

Torch-on bitumen sheets are melted onto a primed surface with a gas torch, giving a fully welded bond but needing hot works control. Self-adhesive sheets have a sticky underside covered by release film and bond cold to a primer. In Saudi Arabia self-adhesive sheets suit occupied buildings and walls.

How long does it take to get bituminous membranes in Saudi Arabia?

Saudi-made APP and SBS sheets are usually available from stock in Riyadh, Jeddah and Dammam within days. Imported sheets and specialist grades depend on shipping and SABER certification and can take several weeks, so check the exact code and stock position before committing to a programme.
